Story from Wat Pah Nanachat, Thailand:
It was Christmas and the foreign monks had decided to celebrate it. They invited some laypeople as well as Ajahn Chah to join them. The laypeople were generally upset and skeptical. Why, they asked, were Buddhists celebrating Christmas? Ajahn Chah then gave a talk on religion in which he said, “As far as I understand, Christianity teaches people to do good and avoid evil, just as Buddhism does, so what is the problem? However, if people are upset by the idea of celebrating Christmas, that can be easily remedied. We won’t call it Christmas. Let’s call it ‘Christ-Buddhamas.’ Anything that inspires us to see what is true and do what is good is proper practice. You may call it any name you like.”
